Exam Marks & Negative Marking Calculator (1/3, 1/4, 0.25)
Estimate exam marks from correct and wrong answers. Use exact one-third, one-fourth, fixed 0.25 or custom penalties and see your net score and accuracy.
How to use this tool
An answer key helps you estimate your performance before an official scorecard is published. This exam marks and negative marking calculator combines correct answers, wrong answers and the marking scheme into an estimated raw score. It also shows attempted questions and accuracy. Use the official provisional or final answer key for the relevant paper and shift, rather than relying on an unrelated examination pattern.
Count your correct and incorrect responses, then enter the marks awarded for one correct answer. Choose one-third or one-fourth when the penalty is that fraction of the marks assigned to the question. Choose fixed 0.25 only when the rule deducts exactly a quarter of a mark per wrong response. A custom option accepts a penalty in marks. Press Calculate Score after checking all values.
The calculation is correct answers multiplied by marks per correct answer, minus wrong answers multiplied by the selected penalty. Unattempted questions are not included unless your examination has a separate rule. For sections with different marking schemes, calculate each section separately and combine their scores. The displayed result does not include normalization, bonus marks, deleted questions, objections or revised keys. Only the recruiting authority can issue the final score.
Frequently Asked Questions
Is one-fourth negative marking the same as 0.25 marks?
Only when each correct answer earns one mark. If a correct answer earns two marks, a one-fourth penalty deducts 0.5 marks. Fixed 0.25 always deducts 0.25 marks regardless of the reward.
Does the calculator round one-third to 0.33?
No. The preset uses one divided by three internally, avoiding repeated 0.33 approximations. The final displayed score is rounded for readability, so a repeating decimal may appear as a short decimal.
Can this result predict selection or the final cut-off?
No. It is an estimated raw score, not a selection prediction. Normalization, category rules, vacancies and the official final answer key can affect published results and qualifying marks.
